Reaction Conditions

Reaction Steps

A dry, round bottom flask containing 41.2 (0.72 g, 2.53 mmol) and DCM (9.0 mL) was cooled to 0° C. After 15 minutes, thionyl chloride (1.0 mL, 13.7 mmol) was carefully added dropwise at 0° C. Upon complete addition of thionyl chloride, the mixture was allowed to warm to room temperature and stirred overnight. After 20 hours, the reaction was concentrated under reduced pressure. The residue was then purified by flash chromatography (SiO2 gel 60, eluted with 0%-15% EtOAc in hexanes). Fractions containing the desired product were combined and concentrated to provide 41.3 as a colorless oil (0.57, 74%). 1H NMR (500 MHz, CDCl3) δ ppm 7.54 (1H, d, J=2.0 Hz), 7.25 (2H, m), 7.04 (1H, d, J=7.4 Hz), 6.90 (3H, m), 4.65 (2H, s), 4.05 (2H, m), 1.43 (3H, t, J=7.0 Hz), 1.24 (9H, s).
